파이참에 강의자료와 같은 코드를 실행했는데 자꾸 오류가 납니다.

입력한 코드와 오류를 첨부하겠습니다.

class Father(object):
    strHometown = "Jeju"
    def __init__(self):
        print("Father is created")
    def doFatherThing(self):
        print("Father's action")
    def doRunning(self):
        print("Slow")

class Mother(object):
    strHometown = "Seoul"
    def __init__(self):
        print("Mother is created")
    def doMotherThing(self):
        print("Mother's action")

class Child(Father, Mother):
    strName = "Moon"
    def __init__(self):
        super(child, self).__init__()
        print("Child is created")
    def doRunning(self):
        print("Fast")

me = Child()
me.doFatherThing()
me.doMotherThing()
me.doRunning()
print(me.strHometown)
print(me.strName)

Traceback (most recent call last):
